Advances on genetic transformation of cotton shoot apical meristem via gene - gun bombardment 以棉花茎尖分生组织为受体进行基因枪轰击转化的研究
It is implicated in the uptake of calcium , the development of apical meristems , and pollen germination 它还与钙的吸收，顶端分生组织发育和花粉萌发有关。
Primary growth growth derived solely from meristems present in the embryo , i . e . apical meristems 初生生长：指完全起源于胚芽分生组织即顶端分生组织的生长。
The term is used particularly in relation to a part of the apical meristem that later differentiates further 该名词也用于指随后进一步发育的顶端分生组织。
Studies on tip meristem culture rapid propagation and induction of in vitro stolon of manyflower betony stachys floridana schuttl . ex benth 银条茎尖培养快繁及离体根状茎的诱导
Leaf is the first lateral organ produced by the activity of the shoot apical meristem ( sam ) 摘要叶片（包括子叶）是茎端分生组织产生的第一类侧生器官，在植物发育中具有重要地位。
Protophloem the first - formed primary phloem , differentiated from the procambium in the region just behind the meristem 原生韧皮部：最早形成的初生韧皮部，由位于分生组织中的原形成层分化而来。
Quiescent center a group of cells in the center of the apical meristem in which mitotic divisions are rate or absent 静止中心：在根的顶端分生组织中心区域的一些细胞，它们几乎不进行有丝分裂。
And development foregrounds is that propagation coefficient of the tip meristem culture is high and the range of increasing in yield is clear 茎尖组织培养前景广阔，具有繁殖系数高、增产幅度大等特点。
New necrotic laticifers with cambium - like meristem continue to form in the inner bark and this makes the disease become irreversible 新的坏死乳管和形成层状分生组织继续在树皮内层形成，因而使该病成为不可恢复的。
